The key here is the word, "allowable".  

Does anyone have any actual data as to what levels have actually been 
found in foods?

Global tested soy flour at some considerable expense, since soy has a fairly 
high "allowable" level and found that if there is any, it is non-detectable using
sensitive equipment at a USDA lab.

So, I guess the real question is that although permissible levels are high, how 
often, if ever, are they achieved in practice?
